Quantum-Secure Bitcoin
Technical guides to quantum-secure Bitcoin: how post-quantum signatures, addresses, mining, and migration work on a live network.
From ECDSA to Dilithium→
What changing Bitcoin's signature algorithm actually requires: opcodes, size impacts, wallet changes, and running both schemes in one block.
The 20x Problem→
Why quantum-resistant transactions need bigger blocks, and how every parameter change cascades through emission schedules, witness economics, chain growth, and node viability.
Why Taproot Is Quantum-Vulnerable→
Taproot exposes the public key on-chain, so a quantum-resistant script in a P2TR container is false security. BIP-360's P2MR removes the key path entirely.
